Product Description:
The MKD025B-144-KG0-KN servo motor is built by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. Paired with digital drive controllers, it delivers tightly coordinated rotary motion in packaging lines, semiconductor handlers, and small pick-and-place axes. Its role is to translate commanded current into proportioned torque and speed so that linear actuators, rotary tables, or belt stages follow reference trajectories without cumulative positioning error. This makes the motor suitable for compact automation tasks that require repeatable motion and stable closed-loop control.
It features a centering pilot of 40 mm, allowing the motor nose to seat squarely against the mating surface and keep the air gap concentric. Power and feedback conductors exit on Side B, which helps keep cabling clear when the unit is installed in confined cabinets or beside adjacent machine elements. Terminations are completed inside a sealed connection box, which provides strain relief and 360-degree shielding against electromagnetic interference. At thermal equilibrium, the rotor can supply 0.9 Nm of continuous stall torque, supporting stable low-speed operation and axis sizing. Rotor position is tracked by resolver feedback, allowing the drive to close the control loops as soon as power is applied.
A square mounting interface with a 54 mm flange mates with compact planetary reducers, allowing the motor to fit small drive trains without changing the basic mounting pattern. The sensing system provides absolute (>4096 revs) position data, so the axis can retain position information across many revolutions and avoid routine homing after startup. The output uses a plain shaft, which accepts clamp couplings that minimize runout and avoid backlash from keyed connections. Internal copper geometry follows winding code 144; together with the B-length stator and 025 frame size, it sets the resistance, inductance, and allowable current for axes that share a common DC bus.
